The HSP 502-1 LML Cold Air Intake increases performance while adding a custom look under the hood of your 2011-2012 GM 6.6L Duramax LML! Featuring 4" mandrel bent pipe, HSP's intakes increase flow by removing restriction while also pulling in cold, fresh air from the headlight bezel and fender port. The heat deflection box provides an airtight seal which prevents hot engine temps from entering through the intake. Proven dyno numbers show an increase of 20HP and 58 lb x ft. torque!
